Clinical tests began today of a novel vaccine directed at the three most globally important HIV subtypes, or clades. Developed by scientists at the Dale and Betty Bumpers Vaccine Research Center (VRC), part of the National Institute of Allergy and Infectious Diseases (NIAID), the vaccine incorporates HIV genetic material from clades A, B and C, which cause about 90 percent of all HIV infections around the world.

“This is the first multigene, multiclade HIV vaccine to enter human trials,” no

Microorganisms are cleaning up contaminants in the mud beneath Boston Harbor, and if humans prevent future fuel spills and leaks, the harbor could potentially cleanse itself within the next 10 to 20 years, according to research conducted at the University of Massachusetts Amherst. The findings are detailed in the Nov. 15 issue of the journal Environmental Science and Technology. The work was funded by the Office of

Bacteria in space, beware. New technology to monitor and identify bacteria is in the works.

Dr. George E. Fox and Dr. Richard Willson, researchers on the National Space Biomedical Research Institute’s immunology and infection team, have developed a new technology to characterize unknown bacteria. Its immediate application will be for identifying bacteria in space, but it will eventually aid in diagnosing medical conditions and detecting biological hazards on Earth.

A new molecular tag discovered by scientists at The University of Texas M. D. Anderson Cancer Center may help doctors decide which breast cancer patients need more aggressive treatment and which can forego the potentially toxic course of chemotherapy.

Khandan Keyomarsi, Ph.D., associate professor in experimental radiation at M. D. Anderson, and her colleagues report in the November 14, 2002, issue of the New England Journal of Medicine that high levels of a protein called cyclin E are close

Study by researchers from Syracuse University, Syracuse, N.Y., and Union College, Schenectady, N.Y., to be published in the Nov. 14 issue of Nature

El Niño, the pattern that can wreak havoc on climate conditions around the world, is like a beacon, pulsating through time on a 2,000 year cycle, according to a new study by scientists from Syracuse University, Syracuse, N.Y.; Union College, Schenectady, N.Y., and from the NOAA Paleoclimatology Program, Boulder, Colo., that is being publis

Scientists have shown, for the first time, that changes in a large-scale climate system can synchronize population fluctuations in multiple mammal species across a continent-scale region. The study, to be published in the 14 November 2002 issue of the journal Nature, compares long-term data on the climate system known as the North Atlantic Oscillation with long-term data from Greenland on the population dynamics of caribou and muskoxen, which are large mammals adapted to breeding in the Arctic.
